What's the difference between Git and GitHub?▾
Git is the version control system that tracks changes to your code locally. GitHub is a hosting platform built around Git that adds collaboration features like pull requests, issues, and CI/CD. You can use Git without GitHub, but not the other way around.
What is a pull request?▾
A pull request proposes merging changes from one branch into another, giving teammates a place to review, discuss, and approve the code before it lands. It's the backbone of collaborative development on GitHub.
How do I fix a bad commit?▾
For local commits you haven't pushed, tools like git reset, git revert, and git commit --amend let you rewrite or undo history. Once changes are shared, prefer git revert so you don't rewrite history others depend on.
